Huisman has been awarded a contract to deliver two 250mt Knuckle Boom Cranes for Sea1 Offshore, a Norwegian shipping company. The cranes will be installed on Sea1’s new ST-245-designed offshore energy support vessels, under construction at COSCO (Qidong) Offshore Co., Ltd.
The cranes will feature Huisman’s proprietary Active Heave Compensation (AHC) system, which integrates the crane’s electric setup with the vessel’s DC grid. This innovative design enables seamless interaction with the vessel’s electrical energy storage system, significantly reducing energy consumption during offshore lifting operations.
This marks Huisman’s fourth major contract this year, reflecting growing market confidence in the company’s premium technology. It also follows last year’s significant upgrade to Huisman’s Knuckle Boom Crane series, emphasizing the industry’s shift toward energy-efficient solutions.
Cees van Veluw, Product Director Cranes at Huisman, commented: “With the current surge in newbuilds in the OSV sector, we are witnessing growing demand for high-quality equipment with low energy consumption. Huisman’s Active Heave Compensation solutions address these requirements and include our patented technology for seamless interaction with the vessel’s Electrical Energy Storage System. We are pleased with the confidence both Sea1 Offshore and COSCO Qidong Offshore have shown in Huisman for the delivery of these cranes.”
The Huisman Knuckle Boom Cranes come equipped with several advanced features, including an Active Heave Compensation system designed for both the deepwater main hoist and auxiliary hoist, ensuring stability during lifting operations. For added safety, the cranes are fitted with a main hoist block catcher. With a maximum lifting capacity of 250mt, these cranes are also powered by Huisman’s proprietary energy-efficient technology, which integrates seamlessly with the vessel’s electrical system. Additionally, the cranes offer a remarkable maximum reach of 36 meters, making them ideal for a range of offshore applications.
